Is squared root of 28 a natural whole and integer number

Question

Algebra 1

Answer 1

Keep this in mind:

 

The nth root of a non-perfect nth power is always irrational.

 

√2  ,  ³√9 ,     and    ⁴√17   are all examples of irrational numbers.  2 is not a perfect square, 9 is not a perfect cube, and 17 is not a perfect 4th power.

Answer 2

I assume you meant SQUARE root, not SQUARED root.

 

√28 = √[(2²)(7)] = 2√7

 

This is an irrational number.
